Micro 100 TBB-625 Boring Bar Brazed Solid Carbide Right Hand

Product Description

The MICRO 100 TBB-625 is a brazed solid carbide boring bar designed for precision internal turning operations on CNC and manual lathes. It features a 0.7950 inch minimum bore diameter, a 5/8 inch shank diameter, and an 8 inch overall length. The brazed carbide construction delivers consistent rigidity and wear resistance across a range of ferrous and non-ferrous materials. This bar is suited for machinists and toolroom professionals who require a reliable, ready-to-run boring solution without the need for insert indexing. Right-hand cutting geometry is standard on this model.

The TBB-625 is used in production and job-shop environments where internal diameter finishing and semi-finishing operations demand tight tolerances. Typical applications include bore sizing on workholding components, hydraulic bodies, and precision mechanical assemblies. The 8 inch overall length provides adequate reach for deeper bore applications while maintaining tool stiffness. This bar is appropriate for use in both conventional turning centers and manual engine lathes equipped with a suitable tool holder or boring bar block.

Key Features

• Brazed solid carbide construction for rigidity and long tool life
• 0.7950 inch minimum bore diameter for precise internal turning
• 5/8 inch shank diameter for standard tool holder compatibility
• 8 inch overall length provides reach for deeper bore applications
• Right-hand cutting direction for conventional lathe setups

Compatibility

Designed as an OEM-style boring bar for use in standard tool holders and boring bar blocks accepting a 5/8 inch shank diameter on CNC turning centers and manual lathes.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and locked out per applicable safety procedures. Secure the shank firmly in a compatible boring bar holder or block to the tool holder manufacturer's specified clamping procedure. Inspect the brazed carbide tip for integrity before use and do not use a bar with a cracked or chipped braze joint. Follow your machine tool manufacturer's guidelines for speed, feed, and depth-of-cut recommendations appropriate to the workpiece material.
